* Czech FinMin sees high 2010 borrowing, costs to rise
* Will issue more shorter-term debt, in 3-10 year segment
* Public sector gap to hit 5 pct/GDP next year, then dip

PRAGUE, May 26 (Reuters) - The Czech Republic's 2010 borrowing needs will remain near this year's record high levels and budgets will stay deep in deficit in the following years, Finance Minister Eduard Janota told Reuters on Tuesday.
The Czech Republic's small and open economy has been hit badly by a slump in demand from the euro zone although it has weathered the downturn better than some other central and east European states such as Hungary, which needed a $25 billion foreign aid lifeline.
In an interview, Janota estimated next year's overall financing need at around 260 billion crowns, provided the parliament approves his proposal for the 2010 central state budget, which sees a deficit of 165 billion.
"If I have a deficit of 165 (billion crowns) and if I assume that some 100 billion will again be refinancing, probably the calendar will be again somewhere around 260 billion, give or take," Janota said.
The country needs to roll over about 78 billion in bonds maturing next year, and it was not clear what other debt needed repayment.
This year's gross borrowing is likely to hit 280 billion crowns ($14.66 billion), more than double the planned amount, as the world economic crisis drives up the central state budget deficit by cutting revenues and increasing welfare spending.
The Finance Ministry expects the economy to contract by 2.4 percent this year. Janota said: "We count on a drop of 2.3 to 2.4 percent for this year, (but) it can be even 3 percent or more, nobody knows that now."
Janota, who has worked at the ministry's budget department for three decades, was picked earlier this month to lead the ministry in a caretaker government which will quit after an election in October. His team will however do most of the work on the 2010 budget draft.
Janota acknowledged that a new 15-year bond was not in high demand on the market and was too expensive for the government so the ministry would focus on shorter-term debt, in the 3- to 10-year range.
An inaugural auction of the 5.7 percent coupon bond last week met weaker demand than previous sales of shorter maturity bonds, and sold with an average yield of 5.789 percent.
NO PRESSURE FOR NOW, BUT OUTLOOK BLEAK
Janota said the state would still issue bonds worth about 100 billion crowns this year, including up to 10 percent in a new retail issue for citizens. He would not say whether the ministry planned another euro-denominated bond this year.
He warned financing the state debt could get more difficult in the future as many countries turn to markets to cover growing deficits resulting from stimulus packages and shrinking income.
"We are not under pressure this year and we should have no problem from the financing point of view," he said.
"In the coming years the situation could worsen ... the market will be tighter, theoretically it is possible that yields could rise."
Janota reiterated that the total fiscal gap, which includes the state budget, various off-budget funds, local government budgets and the health insurance system, would hit 5 percent next year.
It should fall to 4.8 percent in 2011 and 4.2 percent in 2012, he said, although this could change with a new government in place.
The finance ministry will issue a new macroeconomic forecast in July and Janota said he may have to change the parameters of the planned 2010 budget should the new forecast be worse.
